Breast cancer is the most common type of malignancy among women, posing a significant health challenge worldwide. This disease can be broadly categorized into two major types: in situ in place and invasive cancers.
The primary distinction lies between these classifications:
In Situ or Non-Invasive Cancer: These are early-stage breast tumors that remn confined within the ducts of milk glands. The most common type is ductal carcinoma in situ DCIS, characterized by a growth in one part of the breast's duct system, which does not spread beyond this area.
Invasive Cancers: This term encompasses all types of cancer that penetrate into surrounding tissues and blood vessels or lymphatic channels, allowing it to spread to other parts of the body. The two mn categories under invasive cancers are:
a. Ductal Carcinoma: This is characterized by the growth of malignant cells within the milk ducts.
b. Lobular Carcinoma: It occurs when cancerous cells form inside the lobules, which are part of the breast's ocrine system.
A further sub-classification of invasive cancers exists based on where they start:
Invasive Ductal Carcinoma IDC: This is a common form that begins in milk ducts and invades surrounding tissues.
Invasive Lobular Carcinoma ILC: It starts from the milk glands and exts into nearby tissue, unlike IDC which primarily invades the milk ducts.
The choice of treatment for breast cancer deps on various factors including its grade, location, size, and stage. This includes surgery, chemotherapy, radiation therapy, hormonal therapy, or targeted therapies deping on whether it is a hormone-responsive tumor estrogen receptor-positive or not HER2-positive.
In , breast cancer is indeed a multifaceted disease that can be categorized based on its invasion level into in situ cancers and invasive cancers. Each type of breast cancer has unique characteristics which influence the treatment approach taken by physicians like Dr. Wang Yan at the Affiliated Tumor Hospital.
As awareness about early detection grows and innovative treatments continue to evolve, understanding these various types becomes crucial for effective management and care. This knowledge empowers patients and healthcare professionals alike in the fight agnst one of the most prevalent cancers affecting women globally.
